[linux-audio-user] kernel2.6: realtime lsm and allcaps=1

Hi to the list, I've installed a Debian Sarge with kernel 2.6.6, jack 0.94 and realtime-lsm 0.1.1 to have the realtime capabilities for the normal user. The default is to set gid=<audio_group_gid>, but I'm not able to start jack from a user in the audio: $ jackstart jackstart: cannot get realtime capabilities, current capabilities are: =ep cap_setpcap-ep probably running under a kernel with capabilities disabled, a suitable kernel would have printed something like "=eip" Neither the any=1 parm does the job. If I reload the module with the allcaps=1, then I can start jack from a normal user. Am I missing something? Is not insecure to run jack via allcaps=1? Anyway, with the 2.6 series I've got a lot of xruns. I've read that maybe the problem is, instead, with the new version of libc. Someone knows more on it, and is there some workaround? Thanks, - Antonio
